Longer manuscripts may be rejected on the basis of length, or be subject to additional page charges. Typing—Manuscripts must be typewritten on one side of white bond paper, 8-1/2 x 11 inches. Dou ble spaceu// text, including tables, footnotes, and reference lists. Margins should be a minimum of one inch. Underscore only where italics are intended in body of text, not in headings. Geographical names, authors names, and names of plants and animals should be spelled out in full. Except for the first time they are used, scientific names or organisms may be abbreviated by using the first letter of the generic- name plus the full specific name. Submit original typescript and one copy. Pages should be numbered consecutively. Place footnotes at the bottom of the manuscript page on which they appear, with a dividing line. Place tables separately, not more than one table per manuscript page, at end of manuscript. Make a circled notation in margin of manuscript at approximate location where placement of a table is desired. Use only horizontal lines in tables. Illustrations—Illustrations should be planned to fit the type page of 4-1/2 X 7 inches, with appropri ate space allowed for captions. Number all figures consecutively with Arabic numerals. If figures are to be subdivided, use capital letters (A, B, C, etc.) to designate subdivisions. Where possible, figures should be grouped compactly into page-size plates. Photographic prints should be cropped to eliminate unnecessary margins. All figures should be securely mounted on stiff posterboard with identifying in formation (author, title of paper, and figure number(s)) placed on the back. If possible, do not submit original drawings, but reduce photographically and submit prints (glossy or matte) no larger than 9 x 14. The Editor cannot be held responsible for lost art work. Two copies of all illustrative material should be submitted. Figure captions should be typewritten, double-spaced, on a separate page, headed "Captions for Figures," and placed in the manuscript following the list of references. Do not attach figure captions to illustrations. References—Citations in the text should be by author and date. Beginning on a separate page at the end of the text, list references cited alphabetically by author. List titles of articles as well as jounral citations. See articles in this issue for proper style in listing references. Examination of articles in this issue will help in conforming to the type of presentation desired. The editorial style of the PROCEEDINGS essentially follows the Council of Biology Editors Style Manual (Third Edition, A.I.B.S., 1972).

Member authors who are retired or not affiliated with an institution may request to have page charges waived. Acceptance of papers will be based solely on their scientific merit, without regard to the author's financial support. VOL. XXIII, NO. 1 FOR THE YEAR 1976 APRIL 1979 JANUARY The 841st meeting of the Hawaiian Entomological Society was called to order by President J. W. Beardsley at 2:00 pm, January 12, 1976, in room 221, National Marine Fisheries Building, Honolulu, Hawaii. Members Present: Beardsley, Brennan, Chang, Goff, Hara, Haramoto, Hardy, Harris, Howarth, Ito, Joyce, Lin, Look, Mitchell, Montgomery, Ota, Radovsky, Sprenger, Steffan, Su, Sugerman, Tenorio, Tsuda, Wong. Visitors: Mr. Mario Maffi (Bishop Museum) and Mr. Cheng-Shing Lin (U. H. graduate student). Finance Committee: Dr. Frank Chang read the Treasurer's report for fiscal 1975. The report was approved. Executive Committee: President Beardsley announced the names of newly ap pointed officers and members of standing committees. Dr. Ron Mau has accepted position of Business Manager. Dr. Samuelson will share the position of editor with Dr. Beardsley and will serve on committees on which the editor is required to serve. A complete list of committees and members will be transmitted to the membership when all spots have been filled. Membership Committee: UH graduate students Robin Rice and Lawrence Pinter were elected to membership in the Society. Unfinished Business: Mr. Tsuda announced that the Society has donated a set of the Proceedings to the Wau Ecology Institute, Wau, Papua—New Guinea. New Business: The President announced appointment of an ad hoc committee to investigate and formulate the Society's role in the ESA meeting in Honolulu in De cember. The committee members are Frank Radovsky, chairman; D. E. Hardy; Er nest Harris; Wallace Mitchell; and members of the Liaison Committee. Program: Drs. Beardsley, Brennan, Chang, Hardy, Ota, Mitchell and Steffan gave reports on the ESA meeting in New Orleans. Notes and Exhibitions Pantomorus cervinus (Boheman): On December 26, 1975, Mr. Ed Petteys, of the State Forestry Division, observed marginal foliar damage on Iliau, Wilkesia gymnoxiphium Gray, growing at 3,000 feet elevation along the rim of Waimea Can yon at Kukui, Kauai. The plant was carefully examined by pulling back the leaf sheath where numerous Fuller rose bettle adults were found. The beetles were the apparent cause of the observed leaf damage. J. K. Fujii. Schistocerca nitens nitens (Thunberg): In a revision of the genusSchistocerca Stal (Orthoptera: Acrididae: Cyrtacanthacridinae), V. M. Dirsh (Genus Schis tocerca W. Junk, The Hague. 1974) has synonymized Schistocerca vaga (Scudder) under the name Schistocerca nitens nitens (Thunberg, 1815). This species has been 2 Proceedings, Hawaiian Entomological Society known in Hawaii under the nameS. vaga since it first appeared here in 1964. G. M. Nishida. Sympherobius barberi Banks: On September 3,1975, U. S. Forest Service re searcher, Jerry Walters, brought in a sample of a back yard planting of pine infested with the Eurasian pine aphid, Pineus pini Kock, from a Kaneohe address. I ob served neuropteran larvae feeding on P. pini, and on the week of September 22 one adult hemerobiid emerged. The adult was identified by Mr. Stanley Higa, Hawaii State Department of Agriculture entomologist, as Sympherobius barberi. This hemerobiid was purposely introduced from Cuernavaca, Mexico in 1929 and has been recorded preying upon Pseudococcus adonidum (L.) and certain other mealy bugs (Insects of Hawaii, Vol. 6). This constitutes a new host record for S. barberi. J. K. Fujii. Sathrobrota badia Hodges: On January 15,1975 I collected twigs from cluster pine, Pinus pinaster, that were infested with needle cast disease, Lophodermium sp., from Kapaakea, Molokai. The male cones on the twigs were also being at tacked by lepidoptera larvae. Adult moths which emerged were identified by Mr. Stanley Higa, as Sathrobrota badia (Family Cosmopterygidae). Based on speci mens deposited in the State Dept. of Agriculture collection, this moth was prev iously collected in 1964 Kamiloloa, Molokai, on P. pinaster male cones by C. J. Davis. However, this record apparently was not published. This is a new state rec ord. J. K. Fujii. Eusphyrus rectus Schaeffer: A larvae of this anthribid beetle was found boring into a dead twig of Pinus pinaster collected on January 15, 1975 from Kapaakea, Molokai. The larva was held in the laboratory and the adult that emerged was iden tified by Mr. Stanley Higa. This is a new island record. J. K. Fujii. Stator pruininus (Horn): This bruchid beetle was found heavily attacking seeds collected from the arar tree, Tetraclines articulata (Vahl) Masters, (Cupressaceae) in September 1975. The arar trees were planted at Lualualei, Oahu for a species trail experiment by the U. S. Forest Service, Institute of Pacific Islands Forestry. This is a new host record for S. pruininus in Hawaii. J. K. Fujii. Xylosandrus compactus Eichhoff: Mr. R. E. Nelson of the Institute of Pacific Islands Forestry brought in a dead branch of Liquidamber formosana Hance (Hamamelidaeceae) from his yard in Kailua, Oahu. The branch, which was 13 in ches long, had four emergence holes of the black twig borer, and contained two active galleries with six and seven larvae respectively. This is a new host record for X. compactus. J. K. Fujii. Platypus externedentatus (Fairmaire): On November 19,1975, forester Patrick Costales and I examined dead and dying swamp mahogany, Eucalyptus robusta, on Tantalus, Oahu. Pole size trees were debarked, and small holes of P. externeden tatus (Platypodidae) were observed. Eggs and larvae of this pin-hole borer were also found in the galleries, which extended deep into the heartwood. This appears to be a new host record for this beetle in Hawaii. Other hosts include A Ibizia, av ocado, Cassia nodosa, Elaeocarpus, Eugenia, Eucalyptus citriodora, Maba and monkeypod (Proc. Hawaii. Entomol. Soc. 7(2): 205; 8(3): 364; 19(3): 337-338, 339). J. K. Fujii.
